Inventor: KIM YONG W
IPC: G01N21/69
Filed: 1990-04-20
Abstract: Procédé et appareil d'analyse spectroscopique transitoire d'un métal en fusion selon lesquels une sonde (10) contenant un laser pulsé de puissance élevée (14) produisant un rayon laser pulsé ayant une forme d'onde d'impulsion sensiblement triangulaire est immergée dans le métal en fusion et irradie une quantité représentative du métal en fusion. Le rayon laser pulsé vaporise une partie du métal en fusion pour produire une colonne de plasma ayant une composition élémentaire représentative de la composition élémentaire du métal en fusion. Avant que la colonne de plasma n'atteigne l'équilibre thermique peu après la fin de l'impulsion laser, un détecteur spectroscopique (241) dans la sonde (10) détecte des inversions de lignes spectrales pendant une première fenêtre de temps court. Ensuite, lorsque le plasma de post-luminance se trouve en équilibre thermique, un second détecteur spectroscopique (242) également dans la sonde (10) effectue une seconde mesure spectroscopique de durée courte. Un télémètre (22) mesure et commande la distance entre la surface du métal en fusion et le laser pulsé (14).

Title: Continuous production of metal strip
Inventor: MULLER HILMAR R
IPC: B22D27/02
Filed: 1991-11-18
Abstract: ABSTRACT            A method of and an apparatus for the continuous production of metal  strips  of  substantially  final  dimensions are disclosed. The molten metal is cast and solidified on an endless,  advancing cooling strip.  In order to obtain a thoroughly laminar discharge of the molten metal onto the cooling strip,  the molten metal flows from a distributer through a duct, of substantially rectangular cross-section with a small cross-sectional height in relation to its cross-sectional width, connected to the distributer. The duct is downwardly inclined in the direction of flow of the molten metal and opens into a casting opening above the cooling strip. The speed of the outflowing molten metal is regulated by employing an electromotive force opposed to the gravitational force to retard the molten metal flowing in the duct.

Abstract: Method and apparatus for screening peat moss material. The method comprises the steps of forming an aqueous slurry of peat moss material and flowing the slurry on a screen to separate fines from coarser particles in the slurry.  A spray of relatively large water drops is directed at the slurry to agitate the coarser particles blocked by the screen in order to dislodge fines adhering thereto, whereby the fines freed from the coarser particles are allowed to egress the slurry through the screen. The water spray also has the effect of clearing the screen of fines which clog the screen openings.  The invention also comprehends a method and apparatus for screening peat moss material, comprising the steps of flowing an aqueous slurry of peat moss material on a sieve to extract from the slurry excessively large particles, and washing the rejects remaining on the sieve to    dislodge   therefrom    smaller   particles of acceptable size which are returned  to the slurry.

Abstract: Frame/slot synchronization is applied to a received Time Division Multiple Access (TDMA) signal and a temporal position of a reference feature is acquired, such as a synchronizing bit stream or preamble, associated with a desired time slot. The desired time slot is but one of a plurality of time slots that comprise a frame. Verification that the acquired temporal position corresponds to the desired time slot is performed by repetitively estimating a temporal position of the reference feature in a subsequent frame and sampling the subsequent frame at the estimated temporal position to determine if the reference feature is present. The temporal position of the reference feature of the desired time slot relative to the frame is maintained over a plurality of received frames.

Title: Dynamic routing-administration
Inventor: BOGART FRANK J
IPC: H04Q3/66
Filed: 1992-08-20
Abstract: Choice of what portions of a dialed number are important and what weight they carry in deciding how to route or otherwise treat a call is customized and made contextually dependent via a call-processing arrangement that uses stored definitions of syntax and grammar of the network numbering plan. The syntax definitions are reprogrammable definitions of individual symbol strings and include the string's associated virtual nodepoint index which indicates the string's influence on call treatment, an indicator of whether digit collection is to continue, an indicator of whether the VNI is to be combined with a VNI resulting from any preceding symbol strings in the dialed number, and an indicator of whether the VNI resulting from this symbol string is to be combined with a VNI of any succeeding symbol strings in the dialed number. The dialed number is parsed to identify therein all included symbol strings, and the definitions of the included symbol strings are used to selectively combine their VNIs to form a resulting VNI that specifies the route or other treatment for the call.

Title: Signal distribution
Inventor: COOK ANDREW R J
IPC: H04H20/80
Filed: 1991-04-10
Abstract: Signals, such as television signals, are distributed from a head-end station (1) via a fibre network (3). The signals are amplitude modulated on carriers at different frequencies, and the different carriers combined to form a composite analogue signal. In the head-end station (1) the composite analogue signal is clipped to reduce the peak-to-mean ratio and the clipped composite signal is digitised. The resulting digital data is transmitted onto the fibre network and is received at an optical receiver (2). The optical receiver (2) reconstitutes the composite analogue signal for reception by a termination. In one example the composite analogue signal has a bandwidth of one octave or less, and is digitised by sampling at a sampling rate below the Nyquist rate.
